Wavrans-sur-l’Aa (in French pronounced as /wavʁɑ̃ syʁ la/, literally Wavrans on the Aa;) is a commune in the Pas-de-Calais department in the Hauts-de-France region of France.[2]
Wavrans-sur-l'Aa is located 13km (08miles) southwest of Saint-Omer, at the D192 and D225 road junction, on the banks of the river Aa. It is home to a site of great ecological interest, which justified the creation of a voluntary nature reserve, which become the Grottes et Pelouses d'Acquin-Westbecourt et Coteaux de Wavrans-sur-l'Aa National Nature Reserve in 2008[3]
The Chemin de fer d'Anvin à Calais opened a railway station at Wavrans-sur-l'Aa in 1881. The railway was closed in 1955.
